Existence Problem. › Mobile data traffic growth      › Due to increased usage on Smartphone’s, Smartphone’s will reach 66 percent of mobile data traffic by 2018. › In the recent years there has been a skyrocket rise in mobile data usage especially due to the large number of smartphones in use.

Possible Solutions › To solve this problem; dramatic increasing in mobile data traffic; there are several solutions › Upgrade the existence infrastructure. › Offloading to Femto-cells › Wi-Fi networks. › Mobile Wi-Max.

Wi-MAX IEEE 802.16d : wireless technology optimized for fixed and nomadic applications. IEEE 802.16e : a mobile Wi-MAX standard targeted for portable, mobile application as well as fixed and nomadic applications in NLOS environments.

Coverage Deployment

Antenna Configuration Since mobile Wi-MAX uses shared resources, the data rate per sector is shared equally among all users currently served under the cell. Due to the low probability that all customers are going to be served in a single base station, it is assumed that at least 10 customers can be served per sector.

Frequency Reuse Scheme

Frequency Reuse Scheme: Frequency reuse of 1 (universal frequency reuse), denoted as (1,1,3), where all the sectors in a base station use the same channel Frequency reuse of 3, denoted as (1,3,3) whereby a channel is used only one of every three sectors in a base station.

Frequency reuse distance Cellular network planning requires that cells using the same frequency be separated by the frequency reuse distance D in order to achieve tolerable signal to interference plus noise ratio . Where R is the radius of the cell, and N is the number of cells per cluster

Future Work

Future Work Backhaul Connectivity Solutions and dimensioning the transport network, which means how many ASN and CSN, needed depending upon the user experience. IP planning so as to determine how to set up correct IP addresses to all the elements in the core service network. This will enable end-to-end IP connectivity for the user sessions.
